Things I liked:Very sturdy, well-made magazine. Things I would have changed:The manufacturer should come up with a seal for the CO2 that resists deteriorating when the CO2 is left in it for more than a day.What others should know:You need to read your airgun manual. The reason I bought another magazine is because the seal for the CO2 stopped holding because I left the CO2 in the magazine for several days. Big mistake. It was pointed out to me by Umarex that it is in the manual.

Things I liked:good quality and the magnetized magazine make loading less tediousThings I would have changed:The process to load the magazine with bb's and install the co2 cartridge is longer then with most other co2 semioauto's.What others should know:A must buy with the c96 bb pistol. Watch the video or read the manuel the loading method is unusual,
